The first main spiral arm, the Wells Line, the 211 defense zone!

As the commander of the defense zone, Otto's face was heavy at the moment.

Of the 1.5 billion warships, only 380 million remain, and less than 100 million of them have maintained their intact combat effectiveness.

This is the real situation on the front line today, in the face of tens of billions of insect swarms, the third-level civilization is very difficult, and those fourth- and fifth-level civilizations are gathered in the base camp, and they will definitely not attack until the last resort.

This is also the reason why Lin Zhen thinks that the Wells defense line can only hold on for a few years.

In Lin Zhen's opinion, this is simply fighting with the Zerg, but can you fight the Zerg with the Zerg?

It was supposed to be a battlefield where high-level civilizations were the main force and low-level civilizations were auxiliary, but now it has become a low-level civilization fighting to the death, and high-level civilizations are watching the drama in the rear!

This is just fooling around!

"Commander, Commander Bert has sent news that the fleet of the Human Federation is already on its way to support!"

Well? The Federation of Humans? The one that was carried hard in the Silver Heart Passage and the Vera Federation?

"Yes, it's them, they've just arrived at the Wells Line, and they've been coming to our aid non-stop!"

The adjutant nodded in confirmation.

"It seems that this Human Federation is different from other fourth- and fifth-level civilizations! Alas, if all the advanced civilizations were like them, where would we suffer so many casualties! ”

"Wooh. Woo.. Woo..!!"

Just as Otto sighed, the alarm suddenly sounded, which made Otto startled.

"What's wrong?"

"Report, surveillance devices have detected a swarm approaching us, 70 billion in number! The distance is 10AU, and it is expected to arrive in our defense area in 42 hours! ”

"70 billion?"

This makes Odo a little uneasy, the previous swarm was less than 50 billion, and it took most of the day to destroy it after losing most of the fleet, and most of the remaining warships were injured, and now there are 70 billion, what do you want to use to resist?

"How long will it take for the warships of the Human Federation to arrive?"

At this moment, Odo also suddenly remembered the Human Federation that was coming to support, and asked anxiously!

"Commander, according to the information from Marshal Belt, it should be another 45 hours to arrive!"

"45 hours... That means we have to hold on for 3 hours? ”

This made Odo very uneasy, now there are only 100 million warships in his hands with intact combat effectiveness, and among the remaining more than 200 million warships, there will be no more than 100 million lightly injured, and the rest are seriously injured or even paralyzed!

In other words, there are less than 200 million warships that can be used for defense, and this number simply cannot organize enough firepower to effectively resist the advance of the Zerg, and once the Zerg rushes into the formation, it will be a ruthless slaughter that greets them.

We have to find a way!

"Immediately carry out emergency repairs to all seriously injured battleships, to the extent that they can fire, and at the same time call death squads in the entire defense zone! We're going to fight it all! ”

"Yes!"

42 hours later.

In the A211 defense area, among the 380 million warships, except for the 20 million that cannot be repaired, the remaining 360 million warships have all been deployed in defensive formations on the defensive line!

In the array, even the battleships that had been paralyzed and were only repaired to the extent that they could fire were dragged to the outermost side, and even some of the battleships did not even have time to repair the life support system, and the crew directly wore space combat suits to control the ship!

And the crews of this part of the battleships are all death squads temporarily assembled in the defense area, and since the moment they stepped on these broken battleships, they are doomed to have no chance of survival.

"Commander Odo, the front section of the swarm is already within our range!"

In the command room, the eager voice of the enemy officer suddenly sounded.

"The whole army opened fire at once, and I used everything I could, and at all costs, organized a swarm to approach! As long as we hold on for three hours, we can live! ”

"Yes, Commander!"

Suddenly, tens of billions of colorful beams of light and energy bombs swept towards the void in front of him at an extremely fast speed.

After more than ten seconds, it can be seen from the tactical image that the front part of the insect swarm obviously paused, and it was only a moment, after all, the third-level civilization weapon cannot kill these insects with one blow, usually no matter how lucky it is, it takes 3-5 rounds to eliminate a bug.

Fortunately, the swarm did not advance very fast, only less than 10,000 kilometers per second, and there were no ejectors.

It's also very strange to say, since the swarm began to continuously attack the Wells line, the spray bugs have rarely appeared, and the swarm composed of basically all fighting bugs has been constantly attacking.

It's as if they're cooperating with the coalition forces to attrition each other.

The artillery fire hit the insect swarm wave after wave, but the effect was not very good, after all, there were only more than 300 million warships, compared to the previous 1.5 billion warships, the firepower was directly several levels weaker.

Ten minutes later, after dropping billions of insect corpses, the front of the insect swarm was also within 100,000 kilometers of the defenders' array, and it was about to rush into the defense line.

At this moment, all the carrier-based fighters in the fleet took off immediately, and tens of billions of fighters rushed towards the swarm frantically!

According to past experience, the damage caused by fighters to the Zerg is extremely limited, so the general defensive battle against the Zerg will not use carrier-based aircraft technology.

But today's A211 defense area is different, under each of its fighters, there is a bomb mounted, and the group of planes is flying and shooting, and there is not much time for the fighter group to encounter the swarm head-on.

The insects also sensed it at this moment, and in this iron lump, relying on their absolute speed advantage over the fighters, the fighting insects also quickly pounced on the fighters.

One of the bugs excitedly pounced on one of the fighters, then raised its right forefoot and slammed it down, splitting the fighter in two, and then preparing to take out the food from the cockpit.

In the cockpit, the pilot looked at the ugly bug in front of him who was a little excited, and smiled miserably, and then pressed a red button in the cockpit!

"Boom !!"

With a loud bang, the bomb carried by the fighter exploded, and a huge fireball covered the pilot and the bug.

Under such an explosion, the pilot is naturally dead!

However, fighting insects will not survive either!

The same scene is repeating itself on the battlefield at this moment, countless fireballs are constantly burning from everywhere, and each fireball represents a pilot pulling at least one fighting worm and dying together!

This incomparably tragic scene is madly stimulating every soldier on the defensive line!

For a time, the entire swarm suffered heavy casualties!
